True - but if I have 3 duplicate lines on top of each other I would need to select and delete them individually. To be clearer - I was thinking of maybe a 'purge' option after the detection of duplicates to automatically delete them for me so by-passing this stage, particularly if I have a large drawing or an imported file!

If I need to laser cut a lot of Architectural shapes for example, the laser cutter would follow all paths 3 times in this instance.

OK thanks, I`ll have a think about it!I too like the idea of a dialog window to work this from.

Stray points - well sometimes when working with Architectural students they invariably use all sorts of CAD/Illustration programs and very often when exporting an Adobe Illustrator drawing file to DWG for example and then opening up with QCAD There are stray points,little dots or extra lines - where they come from I don`t know, but I need to delete them (or rather I get them to delete them :)) before we laser cut a job.

Here's a trick for now on how to delete all entities of a certain type (e.g. all points):- Select everything in the drawing (Ctrl-A).- In the property editor (at the top) select the entity type (e.g. 'Point').- In the property editor, click the plus button beside the layer combo box (this adds a new layer with all entities that are selected and match the type 'Point').- Type a name for the new layer (e.g. 'temp') and confirm.- Delete layer 'temp'.

Not straight forward and not intended as the final solution to this problem, but it can be worth it, especially if the drawing is badly organized and there are many such points to delete.

Nice little trick - thanks, this will speed up the clean-up process and to be honest pretty easy to do!For now this little trick will probably be of use to a lot of people, I think if you have the time it would be worth you sharing this in the 'Tips & Tutorials' section on the forum, if you don`t I definitely will.
